Control your model train layout with a computer.

Yes, it is possible. You can most definitely control your whole model train layout from a single computer. There is lots of different software out there that will allow you to control your locomotives, their functions and points and other cool accessories attached to your DCC layout. It will use an interface to get the computer to talk to the track. These system usually have two middle men, the USB-to-controller interface and the controller. There are some which only have a single middle man, USB-to-track. This means that to will HAVE to use your computer to control it. The cheapest out there seems to be the Hornby E-Link and Railmaster package. This package comes with the interface and the software. It looks very promising and hopefully it will be very good. Although it says it comes with a 1a transformer, apparently you can actually use the Hornby Elite's 4a transformer. My personal opinion is that computer controlled systems are very good. My reasons are that you can view the whole layout with switch points and you don't have to remember the addresses for the locomotives and accessories as it is down for you! This is my personal opinion and you may have your own. Please comment on what you think!
